If you’re an author, and lots of you are, you are going to sign books. Here’s a trick my friend Robert D. Smith taught me.

Always sign in blue sharpie, not black. Why? Well, the publisher can publish in black. Sometimes books are printed with a signature. If you sign in blue though, readers know with completely certainty that you actually signed it. It’s a small thing, but small things can be awesome.

Go blue!”
